Because the factors involved with the classification of winter storms are complex, there are many different definitions of the word blizzard. A major consensus is that in order to be classified as a blizzard, as opposed to merely a winter storm, the weather must meet several conditions: There must be falling or blowing snow, strong winds, and cold or falling temperatures. What the measurements must amount to for a blizzard to be classified as such depends on where you are.
